Abstract A methodology was developed for synthesizing N-acyl-N'-sulfonyl hydrazides through acyl substitution reactions between activated amides and arylsulfonyl hydrazides. Optimization of the reaction conditions revealed that using Cs₂CO₃ as a base 1,4-dioxane solvent at 25 °C 12 hours produced highest yields. Among various tested, N-benzoylsuccinimide found to be most reactive, with reduced reactivity observed N-mesityl-, N-tosyl-, N-Boc-substituted tertiary benzoyl amides. Cross-reactions diverse range N-benzoylsuccinimides successfully corresponding N-acyl-N′-sulfonyl yields ranging from 63% 94%.

A hydrophobic Ni-PTFE modified electrode has been prepared by constant current and cathodic electroplating with a nickel sheet as substrate in PTFE suspension. Then the was used for electroreduction from aromatic amide to diarylimide. The electrochemical characterizations such cyclic voltammogram, EIS, polarization curves, stability have carried out workstation. structure of product diarylimide characterized
